.lt/linneapolis, in the county of Hennepin and lState of Minnesota, have invented certain .new and useful Improvements in Bumper- Beam Draftliggings; and l do hereby declare the following 'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My prese-nt invention has for its'object to improve that type of draft rigging wherein the .coupler baris connected to and has its base of reaction against a bumper beam.

To the above ends, the invention consists of the novel devices and'combinations of devices hereinafter' described and defined in the claims.7

Certain of the features of the construction herein disclosed are set forth and claimed broadly in the companion application S. N. 388,104, filed of even date herewith, and e'n- Draft Rigging.

ln the accompanying drawings which illus'- trate 'the invention, like characters indicate like parts throughout the several` views.

'Referring te the drawings, Figure l is a view partly in' plan and partly in horizontal section, showingmy invention incorporated in the bumper beam and draft bar. Fig. 2 is a view partly in front elevation and partly .in vertical section, with seine parts broken away, showing the parte illustratedin Fig. l; and Fig. 3 is a vertical section taken on the line x3 x3 of Fig. 1.

The bumper beam l is made hollow, being its central portion it is provided with a draft barseat 2 that extends through the beam from front to; rear thereof, and the side walls ofwhich diverge in a rearward direction and preferably also in a forward direction from'point's marked 2a,-

which points are relatively close to the front face of the said beam.

' The draft bar 3, which is short, is also pref* erably cast hollow in steel, This draft bar is4 seated in and extends through the draft bar seat 2, and isv mounted therein with freedom for lateral oscillatory movements and for longitudinal endwise adjustments.- `Said bum-' per beam is formed with two vertically extended cou )ling pin seats 45, the latter of which is located at the rear of the former. A coupling pin 6, which is extended through a vertical seat in the'draft bar 3 at the trans`v verse centerthereof and in li-newith the points 2a, adapted to be passed through either ofthe seats 4--5 of the beam l, to pivotally couple the said draft bar to the-said bumper beam in different adjustments. )As is evident, when'the pin 6 is the seat d, the draft bar wi much farther beyond the -front face of the bumper beam, than when the said pin -is passed through the seat 5. This adjustment affords means for. positioning the draft-bar for 'proper coupling action under various differentarrangements of couplers. lt is, of course, evident that a greater number than twopin seats may be provided in the beam 1 or in thedraft bar, so as to vaterr still further the number 4of possible adjustments of the draft bar.

To reduce the friction between the draft bar and the bcam,'and thereby make the longitudinal adjustments of the draft bar an easy matter when .the coupling pin 6 is removed, an anti-friction roller 7 is mounted in the bottom of the draft bar seat 2. As shown, this roller Tis in `the form of a shaft having wheelliiie rims for engagement with the bottom of the draft bar, and having projecting trunnions that are mounted in seats 8 formed in the bottom of the draft bar seat 2, as best shown in Fig. 3. At its extreme rear end, the draft bar shown is provided with a lock'liey Q which preventsv the draft bar fromboiug drawn entirely out of the beam when the coupling pin, 6 is removed. At its forwardly projecting end, the draft bar 3 terminates in vertically spaced ears 1.0 to which a coupler head (not shown), is ada ted to lbe connected by means of a coupling'pin (not shown).

A' device of the kind described, is espe- "cially adapted for application` to the front end of a locomotive, butmay, of course, be applied to the rear'end of the locomotive or to the ends of cars or tenders.

What I claim is: v

l. Thecombination with a bum er beam, of a draft bar connected thereto wit freedom for endwise adjustments transversely of said beam.

2. The combination with a bumper beam, of a draft bar connected thereto with freedoin for lateral oscillatory movements and for endwise adjustments, substantially as described.

3. The combination with. a bumper beam having at its centralportion a seat that cxpassed through l be projected,

- having at its central portion a transversely I extended seat having diverging side walls,

of a draft bar working in said seat, and

means connecting said draft bar to said' beam with freedom for longitudinal adjustments and for lateral oscillations, substantially as described.

5. The combination with a bumper beam having a transversely extended seat at its central portion, of a draft bar working in said seat, a roller or anti-friction device in terposed between the bottom of said seatand the bottom of said draft bar, and means adjustably connecting said bar to said beam, substantially as described.

bottom of said draft bar seat, anda coup-v ling pin insertible through either of the pin seats in said beam and through the pin seat in said draft bar, to adjustably and pivotally connect said bar to said beam, substantially as described,

In testimony whereof l yalli); my signature in presence of two witnesses.
